Widget: Find the Maximum and Minimum Usual Values

Use either the mean and standard deviation, or interquartile range to identify outliers in your data. If you use the mean and standard deviation, then the minimum and maximum usual values will be calculated as:

{μ - 2σ, μ + 2σ}

If you use the IQR, then the minimum and maximum usual values will be calculated as:

{Q₁ - 1.5·IQR, Q₃ + 1.5·IQR}

Any values outside these ranges are potential outliers.
